Application filedv aiiuary21, 1,921. .Serial No, 438,839.

To' all whom it may conce/ra.'

Ee it known that I,'I-IY1\1AN F. ChiaaiKnN, a citizenof the UnitedStates, residing at Reading, in the county of Berks and yState oflPennsylvania, have invented certain new and useful Improvements inToothbrushes, of which the followingv is a specification.

' This invention relates to improvements in tooth brushes, and theobject in the present instance is to provide in the first place, athoroughly sterile brush.

Another object is to provide a brush which may conveniently be carriedinthe pocket, somewhat in the manner of 'a fountain pen, and in whichthis sterile condition will be at all times maintained.

A further object is to provide means for carrying a supply of toothpaste or lotion within the container in which the brush is carried.

A further object is to provide a removable handle which may serve as aclosure for one compartment of the container, and also for a handle forthe brush member.

The invention is more fully described in the following specification andclearly illustrated in the accompanying drawing, in which Figure 1 is alongitudinal sectional view of my device with the relative parts intheir proper positions, but with the closure cap for the sterilizingchamber open. i

Fig. 2 is an outside, side elevational view l of my device.

Fig. 3 1s a sectional view taken on line 3-3 of Fig. 1. Y v

The numeral 1 designates a container, which may be made of hard rubber,or other like material, and which is formed of two compartments, 2 and3, both of which are open at one end. The compartment '2 isscrew-threaded internally at its open end to receive the end of a screwthreaded handle member 4. This handle member, in addition to theexternal thread 5, is also formed with an internal thread, for a purposetobe described later. This compartment 2 is intended to receive and holda tooth paste tube or like article, 6, and the handle member will serve,when in the position shown in thedrawing, as a closure for thiscompartment.

The other compartment, 3, 'is designed to receive and carry a toothbrush head 17, and in my present case I form this head with a threadedenlargement 8 at one end.

v This brush head is carried inra receptacle 7, made of "any'suitablemateriah and adaptedftjo lit looselyin the compartment 3, andto contain, beside the brush head,a s tferilizingagent, preferably inthe form ofa gran- 11. The receptacle 7 is `open at one end, and when inposition in the compartment 3, it will reach almost to the edge of thecompartment, and I provide a V,closure for both ulated substance,designated by thenumeral v the kcompartment 3 and thereceptacle 7, in

the form of a'single cap 12, attached to the container 1 by means of ahinge 13 and provided with a catch 14 for holding it in closed position.This cap bears against the end of the container and closes thecompartment 3, and it isformed with a lug 15 adapted to enter the openend of the receptacle 7 and form a closure therefor.

Thebrush head is normally carried in the container, as illustrated, andwhen it is desired to use it, the cap is opened, and the brush headremoved. The handle 4 is removed from its engagement with the containercompartment 2 and the enlarged screw-threaded end 8 of the brush head isinserted in the internally screw-threaded end 18 of the handle member,when it will be ready for use; and, the act of removing the handle fromthe container, at the same time exposes the tooth paste tube which maybe dropped out ready for use.

The extreme utility of the device is of course evident, and of someconsequence, but the most important feature of the invention is the factthat I have provided a tooth brush that will'be kept sterile at alltimes, because after using it, the moisture still ad- 1. A tooth brushcomprising a screw-v threaded handle member, a screw-threaded brushVhead, both substantially as described, in combination with a containerformed in two compartments, one of which is adapted to receive thehandle member and the other the brush head, said handle member forming aclosure for the compartment into which it enters, a 'receptaclecontaining a sterilizing agent for housing the brush head while in thecompartment and a closure for both the receptacle and the compartment.

2. In a device of the character described, the combination of a two-parttooth brush, with a container formed in two compartments, one of whichis provided with a re'- movable receptacle adapted to hold a sterilizingagent and the brush head, a cap hinged to the container and adapted toclose lboth the Vremovable receptacle and the compartment in which thereceptacle is located; the other compartment being screw threaded andadapted to receive the end of handle portion of the two part brush, saidhandle being also screw-threadedto receive the end of the brush head. Y

3. The'combination of a casing made in two compartments, each of whichis adapted Y of the 'tooth brus head is located within the container inthe c first named compartment.

4. A self sterlizing tooth brush comprising a two part brush,vacontainer for the brush "head, a sterilizing agent within the container,a receptacle or casing for the. container, a closure Vfor theVcontainer, means in the casing for carryin a supply `of tooth paste andmeans for hol ing the tooth paste in the casing comprising the handleVmember In testimony whereof aHX my signature.
